It's kind of a matter of personal preference, but I've found that 40psi front, 37psi rear helps to negate the understeer you'll find with the factory 35psi front, 35psi rear setting. I run 205/45-17 Dunlop SP Sport 9000 (non-runflat) on 17" OZ Superleggeras (15.5 lbs).

It seems a bit counterintuitive that you'd add more air to help it grip more, but it has to do with tire slip angle. Slip angle is also the reason why a 17" wheel & tire package will make your car handle better than say, a 15" wheel & tire package, given the same rolling diameter.
